Description

Technical Field

[0001] This utility model specifically relates to a connection structure for home decoration grilles, belonging to the field of home decoration technology. Background Technology

[0002] With the diversification of home aesthetics and the personalization of functional needs, decorative grilles, possessing both aesthetic value and practical attributes, are widely used in decorative scenarios such as walls, ceilings, and cabinets, becoming one of the core components of modern home design. Traditionally, the connection between grilles and decorative components (such as partitions and racks) relies on direct fixing with screws, adhesive bonding, or welding. These methods have significant drawbacks: they require specialized tools and techniques, making installation difficult; long-term use can lead to loosening and damage due to thermal expansion and contraction of materials and uneven stress, affecting safety and aesthetics; and once installed, they are difficult to adjust or replace, limiting user creativity and adaptability to different scenarios.

[0003] To address the aforementioned issues, an existing Chinese patent exists: a connection structure for a home decoration grille panel (patent number: 2024224751124), which achieves flexible adjustment and disassembly of the decorative partition panel by setting a connector with metal pins, a fixing wing, a nut, and a screw.

[0004] Using metal needles to initially position the connectors by inserting them into the back plate, and then fixing the partition by using fixed wings for limiting, screws and nuts, improves assembly flexibility to a certain extent.

[0005] However, in large-scale production and multi-scenario applications, it was found that the existing solution still has room for optimization: First, although the metal pins on the connectors can assist in positioning, they need to be inserted into the back panel for fixation, which can easily cause irreversible damage to soft back panels such as polyester fiberboard and wood, reducing the service life of the back panel and the overall decorative integrity; Second, the presence of the metal pins occupies the internal space of the connectors, which limits the number of threads and the thread depth of the nut (usually only 3-4 threads, with a depth of 5-6mm), and imposes strict requirements on the length of the matching screws of expansion accessories (such as different specifications of hangers and decorative line brackets). If the screw is too long, it cannot be fully screwed in, which can easily cause component interference; if the screw is too short, the connection strength is insufficient, and it is easy to loosen and fall off, which narrows the selection range of expansion accessories and limits the multifunctionality and adaptability of the grille decoration system. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by providing a connection structure for home decoration grilles.

[0007] A home decoration grille connection structure, comprising,

[0008] A connector has a first threaded through hole inside, and an inwardly recessed hexagonal groove is provided on the end face of the front end of the connector, the hexagonal groove being in communication with the first threaded through hole.

[0009] A wing plate is connected to the end face of the rear end of the connector. The wing plate has a second threaded through hole that extends along its thickness direction. The first threaded through hole and the second threaded through hole coincide.

[0010] Furthermore, the inner diameters of the first threaded through hole and the second threaded through hole are equal, and the axes of the first threaded through hole and the second threaded through hole coincide.

[0011] Furthermore, the connector has a columnar structure, and the first threaded through hole is opened through the connector along its axial direction.

[0012] Furthermore, the columnar structure of the connector is specifically one of a prism, a cylinder, or a rectangular column.

[0013] Furthermore, the wing plate has a plate-like structure, and the second threaded through hole is located at the center of the wing plate.

[0014] Furthermore, the plate-like structure of the wing plate is specifically one of a circular plate, a rectangular plate, or a square plate.

[0015] Beneficial effects:

[0016] 1. This utility model, through the matching structure of the connector and the wing plate, can be disassembled and assembled without professional tools, which greatly reduces the installation threshold and avoids the problems of easy loosening and difficulty in adjustment in the traditional method. It also eliminates the metal pin and optimizes the threaded hole structure, so that the decorative grille plate is free from puncture damage.

[0017] 2. This utility model breaks through the limitation on the length of the screw rod of the expansion accessory by increasing the number of thread turns and the depth of the first threaded through hole and the second threaded through hole. It can be adapted to partitions of different thicknesses and hangers of different specifications, improving the compatibility of accessories, while ensuring connection strength and preventing loosening during long-term use.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 As shown, a home decoration grille connection structure includes,

[0025] The connector 1 has a first threaded through hole 4 inside, and a hexagonal groove 3 is provided on the end face of the front end of the connector 1. The hexagonal groove 3 is connected to the first threaded through hole 4.

[0026] The wing plate 2 is connected to the end face of the rear end of the connector 1. The wing plate 2 has a second threaded through hole 5 that extends through its thickness direction. The first threaded through hole 4 coincides with the second threaded through hole 5.

[0027] Specifically, connector 1, as the core load-bearing component, has a columnar structure that can adapt to the gap size of the grille plate. After being vertically inserted into the gap, it achieves initial positioning through structural adaptation, without metal pin positioning, thus avoiding damage to the back plate. When it is necessary to adjust the angle of connector 1, a hexagonal wrench can be inserted into the hexagonal groove 3 at the front end, and the connector 1 can be rotated by applying force with the wrench. Since the hexagonal groove 3 is connected to the first threaded through hole 4, it will not affect the subsequent insertion of the screw. The first threaded through hole 4 of connector 1 coincides with the second threaded through hole 5 of wing plate 2, forming a through threaded channel, providing a continuous meshing path for the screw. The screw can be inserted from the second threaded through hole 5 on the side of wing plate 2 until it is screwed into the first threaded through hole 4 of connector 1, and the decorative part is fixed through thread meshing.

[0028] As a technical optimization of this utility model, the inner diameters of the first threaded through hole 4 and the second threaded through hole 5 are equal, and the axes of the first threaded through hole 4 and the second threaded through hole 5 coincide.

[0029] Specifically, since the inner diameters of the first threaded through hole 4 and the second threaded through hole 5 are equal, the external thread of the screw can simultaneously and precisely mesh with the internal threads of the two through holes, avoiding problems such as jamming or excessive gaps caused by differences in inner diameters; the coincidence of the axes ensures that the screw does not need to be adjusted when it is inserted, and can be continuously screwed into the two through holes along the same axis, reducing the risk of thread misalignment during installation. If the axis is offset, the screw is prone to bumping against the inner wall of the through hole, resulting in thread damage or inability to be fully screwed in.

[0030] As a technical optimization of this utility model, the connector 1 has a columnar structure, and the first threaded through hole 4 is opened through the connector 1 along the axial direction.

[0031] Specifically, the outer diameter of the columnar structure can be precisely matched with the width of the grating plate gap. After vertical insertion, the structure achieves initial axial positioning through interference fit, replacing the metal needle piercing positioning of the existing patent and avoiding damage to the back plate. The first threaded through hole 4 passes through axially, allowing the screw to be inserted from the front or rear end of the connector 1, adapting to the installation direction of different decorative parts. The through-hole design ensures that the thread engagement length is maximized, improving the connection strength.

[0032] As a technical optimization of this utility model, the columnar structure of the connector 1 is specifically one of a prism, a cylinder, or a rectangular column.

[0033] Specifically, it covers the gap shapes of mainstream grille panels on the market, and compared with the narrow adaptability of the existing patented single column structure, it can meet the grille panel decoration needs of different styles of modern homes.

[0034] As a technical optimization of this utility model, the wing plate 2 is a plate-shaped structure, and the second threaded through hole 5 is set at the center of the wing plate 2.

[0035] Specifically, the plate-like shape of the wing plate 2 makes its area larger than the cross-sectional area of ​​the connector 1. When the connector 1 is placed into the gap of the grid plate, the wing plate 2 fits against the surface of the grid plate, and its edge extends beyond the outer diameter of the connector 1, restricting the radial movement of the connector 1. Combined with the axial positioning of the connector 1, a two-way limiting is formed. The limiting range of the plate-like wing plate 2 is larger, and the connector 1 is less likely to deviate radially.

[0036] As a technical optimization of this utility model, the plate-like structure of the wing plate 2 is specifically one of a circular plate, a rectangular plate, or a square plate.

[0037] Specifically, compared with the problem of the monotonous shape of existing patented fixed wings, different plate-shaped wing plates 2 can be precisely matched with the style of the grille and the installation scene, improving the overall coordination of home decoration.

[0038] The specific working principle of this solution is as follows:

[0039] Based on the size of the grating gap and the decorative style, a corresponding columnar connector 1 is selected. The outer diameter of its columnar structure is precisely matched with the width of the grating gap. The connector 1 is vertically inserted into the gap between the gratings. The interference fit between the structures is used to achieve initial axial positioning. This process does not require the metal needle piercing of the existing patent, thus completely avoiding damage to the back plate. At the same time, the first threaded through hole 4 opened axially inside the connector 1 can retain sufficient number of thread turns and depth because there is no metal needle occupying space, breaking through the existing limitations of 3-4 turns and 5-6mm.

[0040] The wing plate 2 connected to the rear end face of the connector 1 has an area larger than the cross-sectional area of ​​the connector 1. When the connector 1 is placed into the gap, the wing plate 2 naturally fits the surface of the grid plate, and the edge extends beyond the outer diameter of the connector 1, which initially restricts the radial movement of the connector 1 and lays the foundation for subsequent angle adjustment and fixation.

[0041] If it is necessary to further fix the posture of connector 1, insert a hexagonal wrench into the hexagonal groove 3 recessed on the front end face of connector 1, and rotate connector 1 clockwise or counterclockwise by applying force with the wrench. During this process, the columnar structure of connector 1 rotates smoothly along the inner wall of the grating plate gap without any risk of jamming. After rotating to the target angle, the fixing wings on both sides of connector 1 are perpendicularly attached to the grating strip, and the wing plate 2 continues to be attached to the surface of the grating plate, forming a double limit in the axial and radial directions, ensuring that connector 1 does not shift or shake during subsequent assembly. Compared with the traditional single-point positioning of screws, the stability is significantly improved.

[0042] The first threaded through hole 4 of connector 1 and the second threaded through hole 5 at the center of wing plate 2 form a continuous through-threaded channel because their inner diameters are equal, their axes coincide, and their helical directions are the same. When installing decorative parts such as partitions and brackets, first align the reserved hole of the decorative part with the second threaded through hole 5 of wing plate 2 to ensure that the screw can be inserted along the same axis. Insert the screw from one side of the decorative part and screw it into the second threaded through hole 5 and the first threaded through hole 4 in sequence. Because the parameters of the double threaded holes are matched, the external thread of the screw can be tightly engaged with the internal threads of the two through holes without jamming or excessive gap. During the screwing process, the head of the screw gradually presses against the surface of the decorative part. At the same time, the sufficient number of thread turns and depth of the double threaded holes can accommodate screws of different lengths. Short screws are suitable for thin partitions, and long screws are suitable for thick partitions and brackets. The screw can be fully screwed in to avoid protrusion and interference, and finally achieves a stable fixation of the decorative part.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
